TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 396,686, dated January22, 1889.

Application filed December 5, 1887. Serial No. 256,967. (No model.)Patented in England June 24, 1887, No. 9,018.

To aZZ whom it may concern:

Be it known that we, JAMES H. OURRIER and EUGENE I. BLOUNT, both ofSomerville,

. in the county of Middlesex and State of Massachusetts, have inventednew and useful Improvements in Type JVriting Machines, of which thefollowing is a specification.

This invention is an improvement on the typeovriting machine describedin Letters Patent of the United States granted May 18, 1886,and numbered342,802, and 011 the typewriting machine described in the applicationfiled by ourselves and others February 26, 1887, Serial No. 228,934:, toboth of which reference is made.

The general operation of the machine is similar to that of the machinedescribed in said Letters Patent and said application, the improvementsbeing matters more or less of detail described below, and pointed out inthe claims at the end of this specification.

In the accompanying drawings, in which similar letters of referenceindicate like parts, Figure 1 is a plan view of the improved typewritingmachine, certain portions being represented as broken out the better toexhibit the invention. Fig. 2 is an enlarged perspective view showingthe feed mechanism in detail. Fig. 3 is a plan detail showing theconneetion which actuates the carriage. Fig. at is a vertical sectionshowing the actuatingspring and its immediate connections. Fig. 5 is ahorizontal section on line m, Fig. at. Figs. (3 and 7 are enlargeddetails of certain parts immediately connected with the actuatingspringshown in Fig. 4 and below described.

A is the table or cover, hinged at A to the base B, and O is the hingedframe, constructed substantially as usual. The index-plate D, however,is in this improvement not a part of the frame, but is supported byposts D D, secured to the table or cover, (see Figs. 1 and 2,) so thatsaid index-plate is stationary. Thus the confusion and blurring of theletters which appeared in the movable index-plate are avoided. Screws Dextend down from the index-plate and limit the upward movement of theframe 0.

The feed rack E is secured to the carriage E near its rear edge, asshown, and is engaged by the semicircular plates or pawls a Z), which,by means of their shape, will remain in engagement when the cover A islifted. The pawl a is rigidly secured to the tube or sleeve F, loose onthe rod (Z, (on which the cover A and frame 0 turn,) and said sleeve isprovided with the hub F, provided with the projection F, to which ispivotally secured the horizontal rod G, provided with the thumb-piece G.

The hub F and hence the sleeve F are prevented from sliding on the rod(Z to the left by means of the collar F which is rigidly secured by aset-screw or other wellknown mechanical means to said rod (1.

The rod G is pivotally attached at G to the lower arm of the elbow-leverH, pivoted at H to the standard H, secured to the upper side of thecover A. The upper arm of this elbow-lever is held against the underside of the frame O by means of the spring H", secured by a rivet tosaid elbow-lever, and having its free end held in the hook H projectingfrom said standard H.

The pawl 12 is rigidly secured to the tube or sleeve I, loose on the rod(Z, and said sleeve is provided with a hub, I, provided with theprojection I, to which is pivotally secured the lever 1', whose oppositeend is pivoted to the horizontal lever J.

6 is a supplemental sleeve loose upon the rod d and provided with one ormore notches,

c, of shape to fit over the slotted adjustable stop e, secured to therod (Z by a screw, 6. By means of the stop and the notched sleeve aspace is left between the sleeve 6 and the sleeve 1 equal to thedistance desired between the letters. This space can be varied by havingnotches e of various depths. A spring,

f, secured to the rod 1, an d with itsIfree end caught by the pin f" onthe lever J ,itends to force the sleeve I toward the sleeve 6.

The lever J is pivoted at J to the cover A, and one end engages the rodG by means of the notch g 011 the under side of the latter, while theother end is pivotally secured to the 5 horizontal rod K, pivotallysecured to the lower end of the elbow-lever K, pivoted to the standard Ione of the elbows of said elbow-lever forming the thumb-piece K.

L is a post secured to the rear edge of the base B near its center. Theupper end of this post is provided withradial grooves Ii, (see Fig. 7,)and a disk, N, (see Figs. 4, 5, and 6,) provided with the projection Non its under side,is screwed to the top of said post, said projectionlying in one of the radial grooves L; The disk is further provided withthe hook N.

P is a sleeve upon the post L, and integral with said sleeve is thelever P, which extends forward horizontally between the base B and thecarriage M, constructed substantially as usual. The free end of thelever P (see Fig. 3) is pivotally secured to the link R, which is alsopivotally secured at its opposite end, at R, to the carriage M. Aspring, S, is coiled around the sleeve P, one end being secured to thehook N 011 the disk N and the other end being secured to the lever P.The tension of this spring is regulated by the projection N on the underside of the disk N being moved into one or another of the radial groovesL on the top of the post L. The whole-that is, the post, disk, sleeve,and spring-is covered and protected by a cap, T. The spring is so coiledthat its tendency is to move the carriage toward the left as theoperator faces the machine.

The operation is as follows Then the frame 0 is in its normalposition-that is, raisedthe pawl a is out of engagement and the pawl bin engagem ent with the feed-rack E, as shown in Fig. 2. hen the frameis pressed down by the operating-lever for the purpose of printing, saidframe moves down the upper portion of the elbow-lever H, thus movingrearward the rod G and imparting sufficient rotation to the sleeve F tobring the pawl a into engagement with the feed-rack. At the same timethe lever J is moved on its pivot J by the notch g on the rod G, thusdrawing its opposite end forward, and, by means of the rod I, impartingsufficient rotation to the sleeve I to bring the pawl 11 out ofengagement with the feed-rack. As soon as this pawl is released, thespring f, by means of the rod 1, forces the sleeve I along the rod Duntil it strikes the supplemental sleeve 6. hen the frame 0 is releasedand allowed to rise, the spring H retracts the rod G and draws the pawlat out of engagement, and the coiled spring S, by means of the levers Pand R, moves the carriage M to the left, and with it the feed-rack E onetooth, and the pawl 19, which is then in engagement with it, as far asthe sleeve I will go. This distance is of course the extent of thelongitudinal play of said sleeve, which is regulated by the slotted stop6 and the depth of the notch 6. Pressure upon the handle G directlyoperates the rod G and allows the feed-rack to move forward 1 one toothin order to provide a space between two words. Pressure upon the handleI draws forward the rod K, and, by means of the levers J and I andsleeve I, removes the pawl 11 from engagement with the feed-rackindependently of the pawl a, which is normally out of engagement, andallows the carriage to be moved to the right for a new line.

The lever J is held with its left end against the notch g and its rightend normally pressing the lever I so as to hold the pawl I) inengagement by means of the spring U, secured to said lever, and with itsrear end pressing against the pin U in the cover A. (See Fig. 2.)

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent, is
